Dorset Council has said that repairs have started under the A350 at Lytchett Matravers following the collapse of an embankment.
The collapse was discovered by a Dorset Highways gang emptying gullies along the A350 in December, when they found a section of embankment had slipped away dangerously weakening the road above.
The remediation work will involve thrust boring two new culverts under the road to replace the existing one that has collapsed, as well as rebuilding and reshaping the northbound embankment, shuttering and filling the void under the road.
The southbound embankment will be reshaped, strengthening the damaged southbound carriageway and two new head walls built to keep the new embankments in place.

In addition, while inspecting the road damage, engineers discovered a major gas leak and investigation by SGN confirmed emergency repairs were needed too.
Engineers have been working on the design for the repairs while tracking down landowners for access into private fields to complete the work.

Dorset Council cabinet member for the natural and built environment Daryl Turner said: “Due to multiple issues and the extent of the highway damage, drivers on this route have experienced disruption to their journeys since the end of last year. I’m pleased that we’re now able to start work.
“We’ve looked at several different ways to carry out the repairs and this is by far the least disruptive method, and we’ll be carrying out other maintenance in the area at the same time to make the best use of our resources.
“I’m grateful that our gully-emptying crew found this damage and acted so promptly.”
Construction work will take around six weeks to complete.
